This paper outlines the new economic dispatch model that
deals with scheduling of generating stations when load
occurs. Power generating scheduling is very important
aspect of power system engineering. At present the
scheduling is done human operators at the load dispatch
centers with the help of SCADA. Data is monitored
continuously on SCADA and is used to prepare power
schedule on each day. Each day load forecasting is done
for the next day, based on the previous data for 3-4 years.
The problem with this method is that it does take in to
account of any unpredictable factors. Because of this on
many occasions the scheduling is not perfect. This results
in loss of power, lower efficiency and high cost of
This paper describes a novel and efficient method with
the scheduling of generating station when load occurs.
Here factors like rain at the generating station, amount of
water in the reservoir and amount of water required to
generate one unit of power at each generating station
connected to the grid are taken into consideration. These
factors are used as input to a fuzzy controller which gives
a cost, real generation and reactive generation as output.
The validity and effectiveness of designing the controller
has been applied to more generating stations and the
result s presented and discussed.
